Chemical Structure
Description
As a certified reference material (CRM), 4-Chloro-2-(1-phenyl-1H-pyrazol-5-yl)phenol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 4-Chloro-2-(1-phenyl-1H-pyrazol-5-yl)phenol (CAS 36124-03-5), a certified reference material (molecular formula C15H11ClN2O, MW 270.71 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-2-(1-phenyl-1H-pyrazol-5-yl)phenol (C15H11ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
